To all evito/m. it may concern.'

Be it lnown that I, Trinononn C. Arens, citizen of the United States, residing at St. Ulairsville,y in the county of Belmont and State `of Ohio, have invented certain new and useful improvements in `Traction Devices for 'Nonskid Chains, of which the following is a specification.

This i invention relates to an improved provide a device which may be readily atv taclied to 'the non-skid chains Awhen desired and may as easily be removed therefrom.

And the invention has a still further object to provide a device which may be readily employed in connection with nonskid chains of conventional design and lwhich may also be used upon substantially any conventional inake of motor vehicle.

Other and incidental objects will appear hereinafter.

ln the drawings: i

Figure l is a perspective view of my improved traction device, the device being shown connected to a pair of the cross strands of a nonsltid chain of' conventional design,

Figure 2 is a longitudinal sectional view taken medially through the device, and

Figure 3 .is a detail section showing the normal'shape of the hooks of the device be-v fore being applied.

ln carrying the invention into effect, I employ a body plate lO'whicli is preferably formed from a piece of suitable resilient sheet metal and is provided at opposite sides thereof with reduced opposite-ly directed arms l1. rll`he body plate is curved both longitudinally and transversely to .fit the periphery of a tire and the arms are, of course, similarly curved. At their outer ends, the arms are bent up to forni hooks or keepers l2, the bills 13 of which are offset toward the arms and, as shown in detail in Figure 3 of thedrawings, normally extend .in spaced parallel relation thereto. Riveted or otherwise secured to the body plate are confronting" angle plates 13 seating fiat thereagainst and snugly fitting between he TRACTION DEVICE FOR N'D'NSKID CHAINS.

upstanding flanges of these plates is a longitudinally curved Vtraction call: la extend ing transversely with respect to the arms l1. The upper margins ofthe call; arebeveled to provide a biting edge and engaged through the end portions of said flanges and through the end portions of the callrare rivets l5 firmly securing the' calli in position. This construction provides an arrangement whereby, when the call; has become worn in suoli degree that it must be replaced, the rivets l5 may simply be punched out when the old calli may be removed and a new call( substituted therefor.

As previously intimated,` my improved device is intended for use upon the nonsskid chains of motor vehicles. In Figure l. of the drawings, l have shown the device secured in operative position to a pair of the cross strands lo of a non-skid chain. As will be observed, the device is of a length to extend transversely between the pair of cross strands so that the device as a whole 4will be disposed circumferentially of the vehicle tire to seat flat thereagainst while the call: 14 will extend transversely with respect to the tire upstanding from the tire tread. Since the hook -bills 13 normally extend in spaced relation to the arms ll, as previously explained, said hooks may be readily engaged with the cross strands '1G so that the device may thus be easily applied, and fitting freely through the hooks from the i lower sides of the arms 11 are transversely extending bolts 17 engaged through one of the links of the respective cross strands within the hooks. The nuts at the upper ends of the bolts serve -to hold the bolts against accidental displacement so that said bolts will operate to locl the device against shifting transversely of the tire along` the cross strands, thus maintaining the device in position overlying the tread of the tire. Securing the bills 13 of the hooks at their free end portions are bolts 18 which are fitted through the arms l1 from the lower sides thereof and through the hook bills, bcing equipped at their upper ends with nuts `which may be adjusted for binding. the bills of the hooks against said arms. The device will thus be securely held upon the cross strands while, when desired, the device may i be readily removed.

In use. one of the devices may be arranged to extend between each pair ot cross strands of the non-skid chains of the vehicle and, as

Will be seen, the Callie lll will provide an effective purchase for ther-ear Wheels of the vehicle so that the full trective ell-ort ot Suid Wheels may he realized in passing over ice or Slippery roads or in pulling` out of mud. Furthermore, the device will operate in conjunction With the non-skid chains to overcorne side skidding'ol' the vehicle. l ziccordingly provide e highly effective device for the purpose set forth and, as will now he seen, a device which may be readily eniployed in connection with conventional tire chains as ynow in common use and will operete with efficiency upon substantially any conventional make of motor vehicle.

Having thus described the invention, What is claimed :is new is:

l. The combination witha non-skid chain having L pair ol crose strands, of :i hody plate provided :it its ends with ineens receiving the strands therethrough, ineens euguged through the lirst ineens und through Huid strands locking the pluto rrr-:duet movement along the. strands, und :in upstnuding cull( carried by the plate..

2.
